The advertised item ended up being a poor counterfeit.
Rakuten. Com puts all the responsibility to correct a bad sale on the vendor who just ripped you off. Rakuten.com plays an "arms length" denial position. "Not us"..."we didn't do that!", but they continue to advertise and sell the same product as genuine.
Got my money back only because I used PayPal. THEY know how to support the customer in these situations.
Would NEVER buy another product from the Rakuten.com site.
